From Wikipedia, the free encyclopedia

A hinge is a type of bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation. Hinges may be made of flexible material or of moving components. In biology, many joints function as hinges.


Door hinges

There are many types of door hinges. The main types include:

  • barrel hinge, which is a sectional barrel secured by a pivot.
  • Pivot hinges, which pivot in openings in the floor and the top of the door frame. Also referred to as a double-acting floor hinge. This type is found already in ancient dry stone buildings.
  • Butt/Mortise hinges, usually in threes or fours, which are inset (mortised) into the door and frame. Most residential hinges found in the U.S. are made of steel, although mortise hinges for exterior doors are often made of brass or stainless steel to prevent corrosion.
  • Continuous hinges, which run the entire length of the door (also known as "piano Hinges")
  • Concealed hinges used for furniture doors (with or without self-closing feature, and with or without dampening systems). They are made of 2 parts: One part is the hinge cup and the arm; the other part is the mounting plate. Also Euro/cup hinge.
  • Butterfly Hinges or Parliament (UK) Hinges. These were known as dovetail hinges from the 17th century onwards and can be found on old desks and cabinets from about 1670 until the 18th century. The form of these hinges varied slightly between manufacturers, and their size ranged from the very large for heavy doors to the tiniest decorative hinge for use on jewellery boxes. Many hinges of this type were exported to America to support the home trade's limited supply. They are still found to be both fairly cheap and decorative, especially on small items.
  • Strap hinges - Strap hinges are an early hinge and used on many kinds of interior and exterior doors and cabinets.
  • H hinges - Shaped like an H and used on flush mounted doors. Small H hinges (3" to 4") tend to be used for cabinets hinges, while larger hinges (6" to 7") are for passage doors or closet doors.
  • HL hinges - Large HL hinges were common for passage doors, room doors and closet doors in the 17th, 18th and even 19th centuries. On taller doors H hinges were occasionally used in the middle along with the HL hinges.

Other types include:

  • Counterflap hinge
  • Flush hinge
  • Coach hinge
  • Rising Butt hinge
  • Double action spring hinge
  • Tee hinge
  • Friction hinge
  • Security hinge
  • Cranked hinge or stormproof hinge
  • Lift-off hinge
  • Self closing hinge
  • Butt hinge

Building access hinges

Since at least medieval times there have been hinges to draw bridges for defensive purposes for fortified buildings. Hinges are used in contemporary architecture where building settlement can be expected over the life of the building. For example, the Dakin Building, California was designed with its entrance ramp on a large hinge to allow settlement of the building built on piles over bay mud. This device has been effective.

Other Hinges

  • Butler tray hinge - Fold to 90 degrees and also snap flat. They are for tables that have a tray top for serving.
  • Card table hinge - Mortised into edge of antique or reproduction card tables and allow the top to fold onto itself.
  • Drop leaf table hinge - Mounted under the surface of a table with leaves that drop down. They are most commonly used with rule joints.

From LoveToKnow 1911

HINGE (in Mid. Eng. henge or heeng, from hengen, to hang), a movable joint, particularly that by which a door or window "hangs" from its side-post, or by which a lid or cover is attached to that which it closes; also any device which allows two parts to be joined together and move upon each other (see Joinery). Figuratively the word is used of that on which something depends, a cardinal or turning point, a crisis.

From BibleWiki

(Heb. tsir), that on which a door revolves. "Doors in the East turn rather on pivots than on what we term hinges. In Syria, and especially in the Hauran, there are many ancient doors, consisting of stone slabs with pivots carved out of the same piece inserted in sockets above and below, and fixed during the building of the house" (Prov. 26:14).

Simple English

A hinge is something that connects two objects and lets them rotate. The most common examples are the hinges that connect doors to walls or door frames. To open a door on hinges, one pushes the side far from the hinges and the door rotates around the side with hinges.

Hinges can be very large or very small. Small hinges are used for jewelery boxes and other small things with lids. Very large hinges have been used at the bottom of buildings, to let a building sit on loose soil or mud without breaking.
